Jon Daniels became the eighth General Manager in Texas club history when he was promoted to the position on October 4, 2005.

Under Daniels' leadership, the Rangers have advanced to the postseason for a club record three consecutive seasons. Off-season additions of free agents Yu Darvish and Joe Nathan and trade deadline acquisitions of Ryan Dempster and Geovany Soto had a major impact in the Rangers' regular season success in 2012. A continued strong farm system also resulted in the major league debut of top prospects Mike Olt, Martin Perez, Jurickson Profar, Robbie Ross and Tanner Scheppers.

In addition, the Rangers were selected as the 2012 Topps Organization of the Year that annually highlights the Major League team that has shown outstanding performance, depth, and talent throughout it major and minor league teams. It marked the first time the Washington/Texas franchise has ever been so honored in the 47-year history of the award.

With consecutive World Series appearances in 2010-11, the Rangers join the Blue Jays (1992-93) and the Yankees (1998-2001) as the only franchises to win back-to-back American League pennants in the last 22 years. Daniels joins the Yankees' Brian Cashman (6), the Giants Brian Sabean (3), and the Tigers' Dave Dombrowski (2) as the only General Managers to make more than one World Series appearance with his current team.

The Rangers accomplishments earned Daniels Baseball America's 2010 Major League Executive of the Year. He is just the second Rangers executive to ever earn the award following Doug Melvin in 1998. Daniels was also selected as the 2011 Major League Executive of the Year by the Boston chapter of the Baseball Writers Association of America.

The three playoff appearances represent the culmination of a dramatic seven-year period in which the club completely overhauled its farm system and developed an organizational philosophy based on strong scouting and player development. That has been supplemented by acquiring a talented group of players through trades and free agency.

The recent success has come for the large part with strong player development and scouting. The Rangers were selected as having the number one minor league organization in baseball in 2009 rankings by both Baseball America and ESPN.com. In January 2010, ESPN.com once again gave the Rangers' farm system the top ranking while Baseball America's number two ranking made Texas just the fourth organization in a ten-year span to earn a top two spot on the BA list in consecutive seasons. In 2012, the seven Texas farm clubs combined for a 400-363 record with Frisco, Myrtle Beach, and the Arizona Rangers all advancing to the playoffs.

During Daniels' tenure, the organization has placed a greater emphasis on international scouting, added to the player development, amateur, and professional scouting staffs, and stabilized the leadership in each department. The emphasis has been reinforced by the signing of several highly-touted players in Latin America, and more recently the Pacific Rim. The success in amateur scouting was evidenced by Baseball America rating the Rangers as having the major leagues' best draft in 2008 after placing second in 2007.

Daniels joined the Texas organization in 2002 as a baseball operations assistant. He was promoted to Director of Baseball Operations in October 2003 and Assistant General Manager in July 2004. He spent the 2001 season working for the Colorado Rockies' Baseball Operations Department.
At the time of his appointment as Rangers' General Manager, Daniels was 28 years, 41 days old, the youngest general manager in Major League Baseball history.

A 1999 graduate of Cornell University in upstate New York, Jon earned his degree in applied economics and management. He is a native of New York City.

Jon and his wife, Robyn, were married in November 2003. The couple resides in Southlake with their son, Lincoln (6) and daughters Harper (5) and Charlotte (2).
